OPERATION
SPECIAL FEATURES
The Magne-Sonic Series 200 is a single point level
switch which may be installed in any position in a pipe
or vessel to detect the presence of a liquid.
The Series 200 includes a status indicating LED which
may be viewed through a lens in the NEMA 4X
enclosure cover or with the cover removed, on the
explosion proof model. The LED will flash
approximately once per second when the switch is
.”off” and will remain constantly lit when the switch
is “on”.
The Series 200 has a tuning fork style probe which vibrates
at its natural frequency when in air A piezoelectric crystalsystem is used to create a 1100 Hz vibration in the tuning
fork. As the tuning fork is covered by a liquid or slurry, a
corresponding shift occurs in the vibrating frequency of the
tuning fork. This shift is being monitored continuously and
once a present threshold is exceeded, the output changes
status.
The electronics can be provided with the following options.
24 – 264 Vac, 24 – 60 Vdc SPST output wired in series
with a load, ,
IS NAMUR (Intrinsically safe)
24 - 264 Vac, 24 – 60 Vdc 5 AMP SPDT relay output,
24 – 60 Vdc (3 wire) PNP/PLC wiring or,
2 wire 23 – 25 Vdc step change output, 4.5 to 6.5 mA Dry,
15 to 18 mA wet.
The LED gives an indication that the switch is
functioning correctly and gives a visual indication
of the state of the relay
A fail-safe switch on the circuit board is provided
for the user to select either “make” when dry-the
normal condition-or”make” when wet, as would
be selected for low level duties
FAIL-SAFE HIGH LEVEL DUTY
The fact that this device is vibrating normally when
dry makes it ideal for use in high level detection
applications.

Operation
The 200 Series is a liquid point level switch designed using the principle of a
tuning fork. The 200 Series continuously monitors changes in its vibrating
fork’s natural resonant frequency. When the 200 Series is used as a low alarm,
the liquid in the vessel drains down past the fork resulting in a change of its
frequency; this is detected by the electronics which switches the output
state. Or when used as a high alarm, the liquid rises in the vessel, contacts
with the forks and again the output switches.

Special features
200 Series has a status indicating ‘heart-beat’ LED which can be seen at all
times through a lens in the cover. The LED will flash (once per second) when
the 200 Series is ‘off’ and will be constantly lit when the 200 Series is ‘on’. The
LED gives an indication that the 200 Series is functioning correctly and of
course gives a local visual indication of the state of the wetside.
A mode switch allows the 200 Series to be set to switch from wet to dry
(typically low alarm) or from dry to wet (typically high alarm). You may also
select a time delay from 0.3, 1, 3, 10, or 30 seconds.
A magnetic test point is on the side of the housing, allowing the user to
perform a functional test of the Squing 2. By touching a magnet on the
target the Squing 2 output will change state for as long as the magnet is
present.
Extension
up to 10 Ft.
Electronics
Standard two core cable with any power supply from 24 to 260V ac (24 to
60Vdc) is used to connect 200 Series in series with the load and achieve
direct load switching. The output acts as a simple SPST switch that changes
with liquid presence. Alternatively use the switching function of the SPCO
relay electronics output. 200 Series also has the option of electronics to be
interfaced directly to a PLC using the PNP transistor output model (threewire).
